This is what I came up with the other day:

/castsequence reset=combat Crusader Strike, Judgement, Crusader Strike, Holy Wrath, Crusader Strike, Inquisition, Judgement, Crusader Strike, Exorcism, Crusader Strike, Judgement, Crusader Strike, Templar's Verdict, Exorcism
/cast Hammer of Wrath

Does rely on lucky exorcism procs, but I find that the proc lasts long enough that most of the time you wind up insta-casting it. Without even taking advantage of other procs like Divine Purpose, I was able to do 5800 dps on a dummy at level 84 in greens, which was pretty close to what I was doing when playing the paladin normally.

If you set up a way to monitor the Divine Purpose procs, I imagine you could get more dps out of it. Just have templars verdict bound to some other key you can mash when it's up.

No consecration because it used way too much mana and caused him to go oom very fast.
